charset="utf-8" No functional change. Note: QAPISourceError's info parameter is Optional[] because schema.py treats the info property of its various classes as Optional to accommodate built-in types, which have no source. See prior commit 'qapi/error: assert QAPISourceInfo is not None'. Signed-off-by: John Snow --- Random aside: It may appear clunky to have to type __str__, but after I mentioned it on the Python typing SIG list, it was noted that this is actually one of very few magic methods that has a "known" type in advance, so there wasn't much desire to special case the typing for it.
